Here's the second of our video blog posts. Matt Cutts, the head of Google's webspam team, provides some useful tips on how to optimize the images you include on your site, and how simply providing useful, accurate information in your ALT attributes can make your photos and pictures more discoverable on the web. Ms Emmy Cutts also makes an appearance.

Update: Some of you have asked about the difference between the "alt" and "title" attributes. According to the W3C recommendations, the "alt" attribute specifies an alternate text for user agents that cannot display images, forms or applets. The "title" attribute is a bit different: it "offers advisory information about the element for which it is set." As the Googlebot does not see the images directly, we generally concentrate on the information provided in the "alt" attribute. Feel free to supplement the "alt" attribute with "title" and other attributes if they provide value to your users!
